When specifying optional parameters for Items, what will be used if a value is not specified?

In Zabbix, when optional parameters are defined for Items and a specific value is not provided, the system defaults to using default values. This is designed to ensure that Items have suitable baseline configurations, allowing Zabbix to operate efficiently and effectively without requiring every parameter to be explicitly set by the user. By utilizing default values, Zabbix maintains consistent behavior and functionality across its components, and it minimizes the risk of misconfiguration, ultimately making it easier for users to set up and manage their monitoring environment.

Default values are essentially pre-defined settings that guide the operation of the respective Items in Zabbix. They allow the user to get up and running with minimal input while still enabling the monitoring of essential metrics.
